Drug Overview

MUCUS RELIEF DM is a medication that combines two active ingredients: Guaifenesin (1200 mg) and Dextromethorphan Hydrobromide (60 mg). It is classified as an expectorant and cough suppressant, designed to help you manage symptoms associated with coughs and mucus buildup. The Guaifenesin works by loosening phlegm (mucus) and thinning bronchial secretions, making it easier to clear your airways. Meanwhile, Dextromethorphan helps reduce the urge to cough, which can be particularly helpful at night when you’re trying to sleep.

This medication is typically used to temporarily relieve cough caused by minor throat and bronchial irritation, such as that which may occur with the common cold or from inhaled irritants. By making coughs more productive and controlling the intensity of coughing, MUCUS RELIEF DM aims to provide you with comfort and relief from bothersome symptoms.
